注意
Removed. TreeView is now deprecated. You can likely now use TreeView\<int\> instead and not think more about it. But if you were using that identifier to store InstanceID data, you should instead opt to upgrade your TreeViews to use TreeView\<InstanceID\> to get the proper typing.
protected virtual bool CanStartDrag(TreeView.CanStartDragArgs args)

|---|---|
| bool |
Remarks
Override this function so it returns true to enable drag and drop behavior for TreeViewItems.
You control TreeView drag and drop in the following order:\
-
override TreeView.CanStartDrag to enable dragging TreeViewItems.\
-
override SetupDragAndDrop to set which TreeViewItems are dragged.\
-
override TreeView.HandleDragAndDrop to control the drag and drop behavior of the TreeView.\
